Arcadio Blasco: : Cinco esculturas urbanas (1986-1991)

2013

Con las primeras elecciones municipales democráticas en España después del franquismo, los nuevos ayuntamientos establecieron programas para reconstruir las ciudades españolas. Un aspecto de estos proyectos fue la creación de espacios públicos donde la gente pudiera encontrarse en un ambiente agradable. Estas áreas se cerraron al tránsito y se amueblaron con árboles, bancos y un nuevo tipo de esculturas artísticas. En la zona de Alicante, el ceramista Arcadio Blasco, ya conocido en Madrid y en Roma, creó cinco monumentos urbanos de gran escala. Después de veinte años, el destino de cada escultura ha sido diferente: alguna permanece en buenas condiciones, pero otras han sido tratadas de tal …

The EAACI/GA2LEN/EDF/WAO Guideline for the definition, classification, diagnosis, and management of urticaria: the 2013 revision and update

2014

This guideline is the result of a systematic literature review using the 'Grading of Recommendations Assessment, Development and Evaluation' (GRADE) methodology and a structured consensus conference held on 28 and 29 November 2012, in Berlin. It is a joint initiative of the Dermatology Section of the European Academy of Allergy and Clinical Immunology (EAACI), the EU-funded network of excellence, the Global Allergy and Asthma European Network (GA(2)LEN), the European Dermatology Forum (EDF), and the World Allergy Organization (WAO) with the participation of delegates of 21 national and international societies. Urticaria is a frequent, mast cell-driven disease, presenting with wheals, angioe…

Studi greci e latini nell?antica Università di Altamura (1748-1821)

2019

The article tries to highlight, despite the scarse of available documentation, the Greek and Latin studies (language and texts) in the ancient Apulian University in Altamura (1748-1821). Furthermore, on the basis of unpublished archival materials (school registers and student workbooks) it is possible to shed light on the ancient authors explained at school, the teaching methods, and the study practices.

QSAR Modeling ANTI-HIV-1 Activities by Optimization of Correlation Weights of Local Graph Invariants

2004

Results of using descriptors calculated with the correlation weights (CWs) of local graph invariants for modeling of anti-HIV-1 potencies of two groups of reverse transcriptase (RT) inhibitors are reported. Presence of different chemical elements in molecular structure of the inhibitors and the presence of Morgan extended connectivity values of zeroth-, first- and second order have been examined as local graph invariants in the labeled hydrogen-filled graphs. By Monte Carlo method optimization procedure, values of the CWs which produce as large values as possible of correlation coefficient between the numerical data on the anti-HIV-1 potencies and values of the descriptors on the training s…

Synthesis and anti-HIV activity of 2,3-diaryl-1,3-thiazolidin-4-ones

2002

Several 1,3-thiazolidin-4-ones bearing a 2,6-dihalophenyl group at C-2 and a variously substituted phenyl ring at N-3 have been synthesized and tested as anti-HIV agents. The results of the in vitro tests showed that some of them proved to be effective inhibitors of HIV-1 replication.

Antiretroviral genotypic resistance in plasma RNA and whole blood DNA in HIV-1 infected patients failing HAART

2008

The extent to which HIV-1 proviral DNA mutations cause clinically relevant antiretroviral resistance is still controversial. Paired plasma HIV-1 RNA and whole blood DNA were compared in patients failing HAART to investigate if the additional knowledge of archived mutations could improve the selection of potentially active drugs. Seventy-three HIV-1-infected patients with first/second HAART failure were studied before starting a new regimen based on RNA genotyping. Follow-up data after a 12-week therapy were available. DNA genotyping was retrospectively performed on stored whole blood samples and mutational profiles were compared to those from RNA. The mean number of IAS pol mutations was si…

Oxidative Stress and Mitochondrial Impairment After Treatment with Anti-HIV Drugs: Clinical Implications

2011

Thirty years after the discovery of HIV infection, there are numerous antiretroviral drugs that control the disease when administered in a potent combination referred to as Highly Active Antiretroviral Therapy (HAART). This therapy reduces the viral load and improves immune system reconstitution, leading to a significant reduction of HIV-related morbidity and mortality. However, HAART does not completely eliminate HIV, so treatment must continue throughout the patient's life. Prolonged use of HAART has been related to long-term adverse events that can compromise patient health. These deleterious effects have been reported for the majority of antiretroviral drugs and are the most common caus…

Profile of leukocyte-endothelial cell interactions induced in venules and arterioles by nucleoside reverse-transcriptase inhibitors in vivo.

2013

Background There is controversy regarding cardiovascular (CV) toxicity of the nucleoside reverse-transcriptase inhibitors used to treat human immunodeficiency virus infection. Methods We evaluated the effects of nucleoside reverse-transcriptase inhibitors on leukocyte-endothelium interactions, a hallmark of CV diseases, in rat mesenteric vessels using intravital microscopy and in human arterial cells using a flow chamber system. Results Abacavir and didanosine increased rolling, adhesion and emigration in rat vessels. These effects were reversed with antibodies against Macrophage-1 antigen (Mac-1) or intercellular adhesion molecule 1 and were reproduced in human cells. Lamivudine, zidovudin…

Serum Malondialdehyde Correlates with Therapeutic Efficiency of High Activity Antiretroviral Therapies (HAART) in HIV-1 Infected Children

2002

Serum malondialdehyde (MDA) levels are increased in human immunodeficiency virus (HIV)-infected children, as it happens also in infected adult individuals. Introduction of high activity antiretroviral therapy (HAART) has promoted an intense decline in morbidity and mortality of these patients. Here we present data on the effect of HAART on serum MDA of HIV+ children and compare them with levels prior to HAART. MDA levels reflect, as other markers do, the HAART-induced clinical improvement and probably also the pro-oxidant/antioxidant side effects of the different drugs used. The results herein allow the proposal of including serum MDA levels as an additional parameter for the clinical manag…
